A catalog of more than 300 late type stars which display maser line radio emission in OH, H2O or SiO molecules has been compiled. About two thirds of the objects have been identified with optical or infrared optics, mostly M-supergiants, Mira, or semiregular variables. The catalog contains optical data such as spectral type, period and magnitude, radio flux densities and velocities and infrared flux densities in the region between 0.7 and 20 micrometers. Introduction: The systematic literature search is complete up to January 1, 1979. The catalogue ends with a reference list containing all objects followed by a code number and a list containing the literature belonging to each code number. The literature cited for each object contains all data used, except data from the general catalogue of variable stars, the two-micron sky survey and the AFCRL infrared sky survey. See the source reference for additional information. The catalogued stars are divided in six groups M-supergiant stars Type I OH/IR stars Type II OH/IR stars H2O/IR stars without detected OH-emission SiO/IR stars Objects undetected in the optical or infrared
